Hello Ahmed, how are you? I am Saif from UAE I liked the program and your effort is very impressive My question is if I want to change the switched switch to a normal switch that is open and closed. Is it possible and how do I do the program on ESP8266? Please help me, my dear brother.

Instead of push button I used a normal switch. If I turn on the switch the relay will continuously on and off, How to solve it sir?

esp32 wifi led light not glowing.

how can i connect all room on one esp

my question is if my internet is down then how to control relay ?

I created the Android App following exactly the steps, installing in three differents phones and after 0.5 seconds the app leave and it doesn't work. I tried also with the original .aia file and again it didn't work. Can you please check the .aia file of github if it's the right one?
